Best practice - check for live articles in a specific context
Using Textpattern 4.8, what’s the best practice route for checking if there are live articles in a given context (e.g. category1)?
The old school way I did this, back when I needed to, involved using an article form that output a 1 if the article was live, and nothing if it was any other status. I used an article__custom tag to output all articles in a given section, with optional category1 and/or category2 checks, and dumped that to a variable, which was then empty (i.e. no live articles) or not empty (i.e. one of more live articles). I could then check the variable and do things based on whether there were articles (or not). A bit clunky, but it worked.
This has a faint whiff of being yield and if_yield territory these days, but I’m waaaaaay out of the loop on recent Textpattern tag stuff, so this might be off track.
How would you do it?

No breaking news here, you still have to query db. Few general principles are
- reuse: if you need to output these articles later, store the complete block rather than
1in<txp:variable name="has_articles" />. You can test it for emptiness with<txp:if_variable name="has_articles" value />and output<txp:variable name="has_articles" />rather than querying db again. - or even don’t store it but use
<txp:evaluate test="article_custom" />:
<txp:evaluate test="article_custom">
<txp:tags_to_output_conditionally />
<txp:article_custom category="..." />
